Application lcd January 6,1888. Serial No. 259,965.

To @ZZ whom t may concern:

Be it known that I, HENRY T. CLAWSON, a citizen of the United States,residing at Newark, in the county of Essex and State of New Jersey, haveinvented certain new and useful Improvements in Ice-Shaving Machines, ofwhich the following specification is a full, clear, and exactdescription.

This invention relates more particularly to machines for shaving ice bymeans of a cutterl'iead revolving in or at the end of a tubularice-holder; but it may of course be applied to any machine for shavingice or other purpose to which it is or may be adapted.

In iceshaving machines of the above description it is important to havethe knives or cutters extend outward (i. e., radially, or nearly so)from the center of the cutter-head practically to the inner wall ot' theice-holder, so that they may remove the ice from the whole face otablock in the ice-holder and not leave a core or other projection toarrest or interfere with the advance of such block.

The prcsentinvention consists in a new coustruction of cutter-head andin the combination ot' the same with an ice-holder, especially one inthe iorm ofa curved tube of about the same width or diameter as thecutter-head.

In the accompanying drawings, which form part of this specification,Figure I is a longitudinal vertical section of an ice-shaving machineprovided with a cuttenhead constructed in accordance with the invention;Fig. II, a face view of the cutterAhead, and Fig. III a back view of thesame.

The cutter-head is composed of a hub, A, with arms l,and plates B,fastened to said arms, each of said plates being a sector of a circle,(a semi-circle, as showin) and each having a lip, 2, which extendsradially from the center of such circle, is bent outward from the bodyof the sector, and has its edge sharpened to form a knife. Such platesare secured to the hub A with the inncrcorner, 3, of the lips or knives2 in the line of the axis ofthe hub, so that each knife-edge extendsradially from the axis or center of the cutter-head and will remove theice from a block Without leaving a core. rlhese plates are or may bestamped out and have screw-holes punched therein by suitable dies andthe lips 2 are bent out, tem- (Xo model.)

pered, and sharpened. The plates are then ready to be fastened in placeon the hub A by means of screws 5, tapped into the ends of the arms l.The spaces 6 for the passage ot' the shaved ice being formed between thelips 2 and the adjacent edges ofthe adjoining plates, no slitting orslotting of the cutter-head is necessary.

The arms l are made toA project forwardin the direction of the axis ofthe cutter-head, so as to leave between them a hollow space, 6, in thefront of the hub A, behind the plates B, into and through which spacethe shaved ice may freely pass. The cutter-head thus made is strong,light, effective, easily made, cheap, and with no parts to get out oforder or to require adjustment by the user. The knives can be temperedvery hard without danger of breaking. When the cutting-edges are wornoff, the old plates can be removed and replaced with new ones bythe userwithout any difiiculty and at a very slight expense.

In the machine the new orimproved cutterhead AB is preferably mounted ona horizontal shaft, C, and placed upright in the lower end of a tubularcurved ice holder, D, in which is placed the ice to be shaved, afollower, E, connected with a hand-lever, E, being employed to force theicc against the cutters.

The ice-holder has about the same width or diameter as the c11tter-head,so that theknives act on both sides of the axis. On theopposite side of the cutter-head from theice-holder is a shaved-icechamber, G, containing a removable drawer, H, into which the shaved icefalls. The plesence or absence of this chamber and drawer is notmaterial to theinvention.

I claim as my invention or discovery- 1. The cutter-l1ead composed of ahub with forwardly-projecting arms and a number ot' separate datplates,\vhich are attached to said arms and lie in a common plane atright an gles to the axis of said hub, each plate being in the form ofasector whose center of curvature coincides with the axis of said hub,and having along one of its radial edges a lip, which is bent outwardand is sharpened to form a knife or cutter, and the said arms beingseparated from one another and having IOO their outer ends at a distancefrom the axis of said hub, so as to leave a clear'space between theinner end of the hub and the said sectorshaped plates at the centerofthe cutter-head, substantially as described.

2. The combination,with the ice-holder and the follower, of thecutter-head arranged at the end of said ieeholder, and composed of a hubwith forwardly-projecting arms and a number of separate iiat plates,which are attached to said arms andlie inaconinion plane at right anglesto the axis of said hub7 each plate being' in the forln of a sectorwhose center of curvature coincides with the aXis of said hub7 andhaving along one of its radial edges a lip which is bent outward and issharpened to form a knife or cutter, and the said arms being separatedfrom one another and having their outer ends at a distance from the axisof said hub, so as to leave a clear space-between the inner end of thehub and the said sectorshaped plates at the center of the cutter-head,substantially as described.

In testimony whereof I have signed this specification in the presence oftwo witnesses. 2 5
